-Improved VF stability, thanks to changes from Ryan Stone, and Juniper. - RSS fixes in the ixlv driver - link detection in the ixlv driver - New sysctl's added in ixl and ixlv - reset timeout increased for ixlv - stability fixes in detach - correct media reporting - Coverity warnings fixed - Many small bug fixes - VF Makefile modified - nvm shared code needed - remove unused sleep channels in ixlv_sc struct Submitted by: Eric Joyner (committed by jfv) MFC after: 1 week
